[0020] Next, the technical solutions in the embodiments of the present utility model will be described clearly and completely in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] For the convenience of understanding the present utility model, the present utility model will be described more comprehensively below with reference to the relevant content. Several embodiments of the present utility model are given. However, the present utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present utility model more thorough and comprehensive.

[0022] It should be noted that when an element is referred to as being "fixedly provided on" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this utility model belongs.

[0025] Example 1, please refer to Figure 1 and 2 , an early warning cushion plate for an electric vehicle battery fire, including a cushion strip body 1. A plurality of card slots 3 are provided on the upper surface of the cushion strip body 1. A temperature-sensitive optical fiber 4 for monitoring the temperature of the vehicle battery pack is arranged inside the card slot 3, and the temperature-sensitive optical fiber 4 is externally connected to a signal processing end. Both sides of the cushion strip body 1 have wear-resistant inclined surfaces.

[0026] The temperature-sensitive optical fiber 4 is inserted into the card slot 3 inside the cushion strip body 1, and the temperature of the parked battery pack is monitored through the temperature-sensitive optical fiber 4. When it is found that the temperature rises, the temperature-sensitive optical fiber 4 will deform due to the temperature change, thereby changing the propagation path and reflectivity of the light in the optical fiber, causing a change in the light intensity signal, and thus obtaining information on the temperature change.

[0027] Both sides of the cushion strip body 1 are provided with inclined slopes. A plurality of grooves 2 are equidistantly arranged on the slopes on both sides. The cross-section of the groove 2 is semi-circular. The temperature-sensitive optical fiber 4 is limited and clamped inside the card slot 3. A plurality of bottom grooves 5 are provided on the bottom surface of the cushion strip body 1. One card slot 3 is provided and is located in the middle position at the upper end of the cushion strip body 1. The lower cross-section of the inside of the card slot 3 is semi-circular, and the temperature-sensitive optical fiber 4 is adapted to the inside of the card slot 3.

[0028] The bottom groove 5 can be used to accommodate the passing of other electric wires to avoid the vehicle crushing the wires. In this embodiment, one card slot 3 is provided, which is located in the middle of the top of the cushion strip body 1, and the entire cushion strip body 1 has the function of a speed bump.

[0029] Example 2, please refer to Figure 3 and 4 , the difference from Example 1 is that: a group of card slots 3 are provided in total, and the two card slots 3 are respectively located at the upper end positions of the slopes on both sides.

[0030] In this embodiment, two card slots 3 are provided, and the temperature-sensitive optical fiber 4 passes through the two card slots 3 in sequence through the ends, which can increase the monitoring range of the battery pack temperature and make the monitoring more accurate.
